Sediment-tester.



THEODORE L. VALERIUS AND OLAF LARSEN, 0F FORT ATKINSO WISCONSIN, ASSIGN- @TATEd BATENT OBS TO CREAMERY IEAGKAGE MANUFACTURING- COMPANY, A CORPORATION OF rumors.

To all whom it may concern.

.Be it known that we, THEODORE L. VALE- RIUS and OLAF LARSEN, citizens of the United States, residing at Fort Atkinson, in the county of Jefferson and State of Wisconsin, have invented certain new and useful Improvements in sediment lesters, of

' hotels and other purchasers of milk, of

records showing the quantity of sediment contained in the milk received. by them.

In the accompanying drawing, Figure'l is a sectional view illustrating a sediment tester embodying our invent-ion, and showing the manner in which it may be used.

' Fig. 2 is a fragmental top plan view of the tester.

The embodiment herein shown of our in vention is adapted to be supported upon the mouth of a milk bottle A and to support in inverted position a bottle B ctuitaining themilk to be tested.

In the form. lllustrated 1n the drawings, the tester comprises a tubular body 1 having 'an annular outwardly-extending flange 2 aoapted to rest upon the mouth of the bottle A. In the flange Zis a suitable number of vent openings 3 forming an outletfor the air. displaced from the receiving bottle A by the incomingfiltered milk. Near the upper end of the body 1 is an annular outwardly-extending flange 4 to support the bottle B. Herein we have shown the flange,

4 as consisting'of a rubber ring adapted to lie in contact with the seat provided for the ordinary milk-bottle cap, said ring being secured in place by means of a nut 5.

5 are notches in the nut 5 to receive a spanner wrench. If desired, the surfaces of lib the body 1 and the nut fi'which are in contact with the rubber flange 4: may be. beveled, as herein shown, so as to hold said flange Specification of Letters Patent. Application filed August 23, 1912. Serial No. 716,602.

-lightly in place. The rubber flange orgasket 4 forms a liquid-tight joint with the mouth of the bottle B.

The body 1 is provided with an interiorannular. shoulder 7 adapted to support a filter disk 8 of any suitable character and a disk 9 of wire netting or other suitable material. Said disks may be removably held in place by any appropriatemeans, as, for example, a sleeve 10 arrangedlto rest upon the edges of the filter disk, and of'such length as to projectabove the body 1 in order that said sleeve may be conveniently lifted out of its place and returned thereto. The sleeve 10 is frictionally held in place in the body 1, said sleeve being preferably made slightly resilient, as by forming a slot 11 through one side.

Airv is admitted to the upper bottle to counterbalance the atmospheric pressure, and thus permit the milk t6 flow by gravity into' the lower bottle. Herein we have shown an air inlet tube 12 connected to the body 1 and communicating with the interior" 'of said body,- the periphery-of the sleeve 10 being recessed to provide an annular space between said sleeve and said body forthe upwardpassage of air. ,Arubberbulb 13 hav- Patented Feb. 4, 1913.

ing the usual air inlet 1 1 is connected to the outer end of the inlet tube 12 by means 0 e flexible. tube 15. 13 is located the usual check valve 16.

The apparatus may be used for testing either bulk or bottled milk. In practice, the

tester is placed upon the mouth of a'bott-lo containing milk to be tested, the rubber flange 4 being in contact with the cap seat. The bottle and tester are then inverted and placed on the mouth of an empty milk bottle or other suitable container. Airmay now be forced into the upper bottle, whereupon In. the neck of the'bulbthe milk will flow through the sleeve 10 and I through the filter disk 8 andthe screen 9 into the lower bottle. The air displaced from the lower bottle by the incoming filtered milk escapes through the vent 0 e11-- ing 3. When'th'e sampleof milk has con thus filtered, the bottle B is removed, the sleeve 10 withdrawn from the body 1 and the filter disk 8 removed. The filter disk may be readily removed by pressing up w ardly on thewire screen or disk 9, thereby pushing both disks up out of the body 1. After the ,filter diskhas been inspected it may, if desired, be dried and mounted upon ment carried by said body, said body having an air inlet therethrough above said element.

2. As an article of manufacture, a sedi ment-tester comprising a body, a filtering element carried by the body, and air-injecting means attached to the body.

3. As an article of manufacture, asediment-tester comprising a chambered body, a filtering element within the body, an air inlet tube connected to the body and communicating with the interior thereof, and

air-injecting means connected -to said tube.

4;. A sediment tester comprising a tubular body adapted to-be supported upon the mouth of a milk bottle, said body having interior filter-supporting means, a filter disk resting upon said supportingmeans, a tubular element adapted to rest upon the edges of said filter disk and engaging said body to prevent displacement of said disk, 'a-space being provided between said body and said tubular element, and said body having an air inlet opening into said space.

5. A sediment tester comprising a tubular body having an outwardly extending flange adapted to rest upon the mouth of a milk bottle, a rubber gasket encircling the upper portion of said body and adapted to fit into the cap seatof an inverted milk bottle and support such inverted milk bottle, means I for securing said gasket to the body, said body having an internal annular shoulder, a screen resting upon said shoulder, a filter ing disk resting upon said screen, a sleeve having one end resting upon the'edges of said filtering disk, a space being provided between the periphery of said sleeve and the interior wall of said body, said sleeve extending above the body, and said body having an air inlet therethrough communicating wlth said space.

6. A sediment-tester comprising a tubular body adapted to be supported upon the mouth of a milk bottle, said body having interior filter-supporting means, a filter disk resting upon said supporting means, a tubular element adapted to rest upon the edges of said filter disk and engaging said body to prevent displacement of said disk, a space being provided between said body and said tubular element, and air-injecting means attached to said body and communicating with said space.- s

7. A sediment-tester comprising a body provided, with outwardly-extending means adapted to rest upon the mouth of a milk bottle, a rubber ring encircling the upper portion of said body, means for securing said ring to the body, and a filtering element carried by said body.

8. A sediment-tester comprising a tubular body having an outwardly-extending flange adapted to rest upon the mouth of a milk bottle, an air vent opening being provided in said flange, a rubber gasket encircling the upper portion of said body and adapted to fit into the cap seat of an inverted milk bottle and support such inverted bottle, means for securing said gasket to the body, said body having an internal annular shoulder, a screen resting upon said shoulder, a filtering disk resting upon said screen, a sleeve having one end resting upon the edges of said filtering disk, a space being provided between the periphery of said sleeve and the interior Wall of said body, said sleeve eX-' tending above the body, an air inlet tube adapted to be attached to said body and communicating with said space, and a rubber bulb connected to said air inlet tube.

In testimony whereof we afiiX our signa- 'tures in the presence of two Witnesses.
